Description

The fibers,250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. Then the cable core is covered with a thin polyethylene (PE) inner sheath, which is filled with jelly to protect it from water ingress. A layer of water-blocking material is applied around the cable core to prevent water ingress all the same. After a corrugated steel tape armor is applied. the cable is completed with a PE outer sheath.

Characteristics

        · Good mechanical and temperature performance
        · High strength looes tube that is hydrolysis resistant
        · Special tube filling compound ensure a critical protection of fiber
        · Crush resistance and flexibility
        · The following measures are taken to ensure the cable watertight:
                - Single Fiber Reinforced Plastic as the central strength member
                - Loose tube filling compound
                - 100% cable core filling
                - PSP enhancing moisture-proof
                - Water-blocking material

Standards

        GYFTY53 cable complies with Standard YD/T 901-2001as well as IEC 60794-1.
